[ruby/json] Fix handling out of of range exponent in numbers
Fix: https://github.com/ruby/json/issues/970
If the parsed exponent overflows a `int32_t` passing it
to ryu is incorrect.
We could pass it to `rb_cstr_to_dbl` but then Ruby will emit
an annoying warning, instead we can coerce to `0.0` and `Inf`.
